Position-based quantum cryptography: Impossibility and constructions (2011)

Perfect cheating is impossible for single-qubit position verification (2024)

Considers a generalisation where the input qubits are eigenstates of a $\mathbb{C}^2$ projector chosen uniformly at random. Shows that no finite-dimensional resource state can perfectly attack this protocol

Quantum position verification in the random oracle model (2014)

Considers QPV in higher dimensions carefully and shows unconditional security in the random oracle model

Quantum Secure Key Exchange with Position-based Credentials (2025)

Improved analysis of how to use QPV to provide the authentication within QKD

Instantaneous non-local computation of low T-depth quantum circuits (2016)

Provides a general attack on QPV using an exponential amount of pre-shared EPR pairs in the number of T-gates or T-depth based on the circuit decomposition of the task unitary into Clifford+T gates
